[0020] Example 1
[0021] like Figures 1-3 As shown, the plastic surface spray painting device proposed in this embodiment includes a frame 1 and a grinding mechanism 6. The frame 1 is equipped with a cleaning component and a fan 2. The grinding mechanism 6 includes a mounting frame 61 mounted on the frame 1, an auxiliary frame 63 slidably mounted on the mounting frame 61, a moving rod 64 mounted on the auxiliary frame 63, a moving plate 65 mounted on the moving rod 64, multiple connecting rollers 66 rotatably mounted on both sides of the moving plate 65, a driving component mounted on the mounting frame 61 and the moving plate 65, and multiple grinding components slidably mounted on the moving plate 65. The multiple grinding components slide in contact sequentially, the driving component is drivenly connected to the moving plate 65, and the multiple connecting rollers 66 all roll in contact with the frame 1.
[0022] The cleaning assembly includes a spray frame 11 mounted on the frame 1, a filter plate 8 and a liquid storage tank 7 slidably mounted on the frame 1, a liquid pump 9 connected to the liquid storage tank 7, and a liquid delivery pipe 10 with its two ends connected to the liquid pump 9 and the spray frame 11 respectively. When the workpiece 5 to be treated moves under the spray frame 11, the spray frame 11 sprays liquid onto the surface of the workpiece 5 to wash away the dust adhering to the surface of the workpiece 5. The washed liquid is filtered by the filter plate 8 and then falls into the liquid storage tank 7. The liquid pump 9 sends the liquid back to the spray frame 11 to achieve liquid recycling and reduce resource waste. At the same time, the spray frame 11 is also connected to an external water pump to ensure that the spraying force of the spray frame 11 remains stable.
[0023] In this embodiment, multiple evenly distributed clamping frames 4 are provided on the conveyor belt 3. The clamping frame 4 is detachably provided with the workpiece 5 to be processed. The clamping frame 4 transports the workpiece 5 to be processed to the bottom of the grinding mechanism 6. Multiple grinding components adjust their height according to the surface texture of the workpiece 5. Then, the drive component drives the moving plate 65 to move back and forth. The moving plate 65 drives multiple grinding components to move back and forth at high frequency, thereby avoiding the problem of not being able to grind due to the uneven surface of the workpiece 5. When the workpiece 5 passes under the grinding mechanism 6, the fan 2 blows the dust ground off the workpiece 5 to other places where the dust can be processed. Then, the cleaning component cleans the surface of the workpiece 5.
[0024] Example 2
[0025] like Figure 2 and Figure 3 As shown, this embodiment of the plastic surface spray painting device, compared with the first embodiment, includes a drive assembly comprising a motor 62 mounted on a mounting frame 61, a gear 67 mounted on the output end of the motor 62, and two racks 68 disposed opposite each other on a moving plate 65; the gear 67 is meshed with both racks 68. The gear 67 has multiple meshing teeth, all distributed on one side of the gear 67, and each meshing tooth is always meshed with only one rack 68.
[0026] In this embodiment, the motor 62 drives the gear 67 to rotate. During the rotation, the gear 67 will only mesh with one rack 68. The gear 67 will mesh with the rack 68 depending on the direction in which the multiple meshing teeth on the gear 67 are facing. The staggered meshing of the gear 67 with the two opposite racks 68 will cause the two racks 68 to drive the moving plate 65 to reciprocate.
[0027] Example 3
[0028] like Figure 3 As shown, this embodiment of the plastic surface spray painting device, compared with the first embodiment, includes a sanding assembly comprising a lifting frame 69 slidably mounted on a moving plate 65, a spring 610 mounted on the lifting frame 69, a sanding frame 611 detachably mounted on the lifting frame 69, and multiple filling cotton 612 arranged sequentially from top to bottom on the sanding frame 611; sanding blocks are provided on the outer surfaces of the sanding frame 611 and the filling cotton 612. The cross-section of the sanding frame 611 is arc-shaped. Multiple clamping cylinders are rotatably mounted on the auxiliary frame 63, and all of the clamping cylinders are in rolling contact with the mounting frame 61. Multiple pairs of lifting rollers are rotatably mounted on the moving plate 65, and all of the multiple pairs of lifting rollers are in rolling contact with the lifting frame 69, thereby avoiding discontinuous lifting and lowering due to frictional resistance during the lifting and lowering process of the lifting frame 69.
[0029] In this embodiment, the workpiece 5 to be processed comes into frictional contact with the polishing frame 611. The workpiece 5 pushes the polishing frame 611 according to its own texture. At the same time, if there is a certain distance between the side of the polishing frame 611 and the workpiece 5 to be processed, the filling cotton 612 will push the polishing block to move to both sides, so that the polishing block can contact the workpiece 5 to be processed for polishing, thereby increasing the polishing range of the device and reducing the polishing dead angle of the workpiece 5 to be processed.
[0030] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
